Description

Technical Field

[0001] This utility model relates to the field of construction tools for building engineering, specifically a manual rebar bending tool. Background Technology

[0002] In construction engineering, bending steel bars is a common material processing activity. Considering efficiency, mechanical bending is mostly used. However, in the early stages of construction when equipment is not available or when processing small batches, manual bending is generally used. Especially for steel bars with a diameter of 16cm or less, the bending force required is small, and mechanical bending is energy-consuming and uneconomical. In addition, the noise from mechanical processing has an impact on the surrounding environment. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a manual rebar bending tool with a simple structure, easy to use and move on the construction site, and suitable for bending small batches of rebars. The technical solution adopted by this utility model is as follows:

[0004] A manual rebar bending tool includes a support frame and a bending handle;

[0005] The support frame includes two side rods arranged on the left and right, at least one support rod, and a bending rod. The support rod and the bending rod are distributed sequentially from back to front and are located between the two side rods. The front end of the side rod is bent downward so that the height of the bending rod is higher than the height of the support rod on the horizontal plane, so that the front bend of the reinforcing bar is below the bending rod and the rear part of the reinforcing bar is above the support rod. The bending handle is a steel pipe fitting used to insert the front bend of the reinforcing bar to achieve bending.

[0006] The aforementioned manual rebar bending tool has an angle gauge and a mounting base on the bending rod. The mounting base can slide along the bending rod, and the angle gauge is magnetically connected to the mounting base.

[0007] The aforementioned manual bending tool for reinforcing bars also includes a pad, which is placed behind the support frame to support the rear of the reinforcing bars.

[0008] The beneficial effects of this utility model are as follows: This manual bending tool supports the reinforcing bars through a support frame and uses a bending handle to bend the reinforcing bars. It has a simple structure, is easy to operate, can be used flexibly on site, and is suitable for manual bending of small batches of reinforcing bars. Attached Figure Description

[0013] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. The following embodiments are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical terms used have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should be noted that the terminology used is for describing specific embodiments only and is not intended to limit the scope of this application.

[0014] This embodiment is a manual rebar bending tool, such as... Figure 1 As shown, it includes a support frame 1 and a bending handle 2. The support frame 1 and the bending handle 2 can preferably be made of corrosion-resistant materials, or have an anti-corrosion coating sprayed on their surfaces to extend their service life.

[0015] The support frame 1 includes two side rods 11 arranged on the left and right, at least one support rod 12, and a bending rod 13. The support rod 12 and the bending rod 13 are distributed sequentially from back to front and are located between the two side rods 11. The front end of the side rod 11 is bent downward so that the height of the bending rod 13 is higher than the height of the support rod 12 on the horizontal plane. In this way, the front bend of the reinforcing bar 4 is located below the bending rod 13 and the rear part of the reinforcing bar 4 is located above the support rod 12. The bending handle 2 is a steel pipe fitting used to insert the front bend of the reinforcing bar 4. By operating the bending handle 2, the reinforcing bar 4 is bent to the required angle.

[0016] Furthermore, the bent rod 13 is equipped with an angle gauge 5 and a mounting base 6. The mounting base 6 can slide along the bent rod 13, and the angle gauge 5 is magnetically connected to the mounting base 6. The angle gauge 5 is a common semi-circular plate with a scale from 0 to 180°, and its bottom is provided with a magnetic material such as an iron sheet. The mounting base 6 is provided with a magnet, so the angle gauge 5 can be magnetically attached to the mounting base 6 and its position can be easily adjusted to accurately measure the bending angle in accordance with the position of the reinforcing bar 4. Alternatively, the angle gauge 5 can be directly removed for use, which is convenient and flexible.

[0017] The manual bending tool for the reinforcing bars also includes a pad 3, which is placed behind the support frame 1 to support the rear of the reinforcing bar 4.

[0018] When using this manual rebar bending tool, a certain number of rebars 4 to be processed are placed on the support frame 1, such as... Figure 2As shown, the front part of the reinforcing bar 4 passes under the bending rod 13 and the rear part is placed on the support rod 12 and the pad 3. The worker can step on the rear part of the reinforcing bar 4 to further stabilize it. Then, the bending handle 2 is operated to bend the reinforcing bar 4 to the required angle. The bending angle of the reinforcing bar 4 is measured and checked by the angle measuring device 5. The bending handle 2 is adjusted in time to ensure accuracy.

[0019] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various changes or improvements without departing from the principles of this application, and these changes or improvements should also be considered within the scope of protection of this application.
